LIQUIDCOOLING DEVICE.

Specification of Letters Patent.

Patented Novias, 1907.

Application filed January '7.1907'. `Serial No. 351.104.

lBe it known that I, ADOLPH KOCH, a citizen of the .United States,'residing at Pasadena, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Liquid-CoolingDevices, of which the 'following is a specification.

My invention relates more particularly to portable liquid coolingdevices and an object thereof is to provide means whereby liquid may becooled as drawn off from a liquid receptacle secured to thel outside ofthe cooling device.

Another object of my invention is to provide a device whereby it ispossible to replace the liquid receptacle with another holding adifferent liquid with little trouble or inconvenience.

Another object is to provide a device, the lower chamber of which may beutilized as a refrigerator While the upper chamber may be uid receptaclebeing removably secured to the outside of the cooling device, thusgreatly increasing the capacity of the refrigerant chamber.

A further object is to provide a device that is economical inconstruction and efficient in operation.

I accomplish these objects by means of the device described herein andillustrated in the accompanying drawings, in which Figure 1."- is a sideelevation of my improved device partly broken away. Fig. 2.- is a frontelevation of my improved device partly broken away. Fig. 3.- is atransverse section taken on line 3 3 of Fifr. 2. Fig. 4.- is alongitudinal section througl the outlet end of the liquid receptacle,showing the construction of the outlet valve. Fig. 5.- is a transversesection .taken on line 5-5 of Fig. 4.

Referring to the drawings, 10 designates a cooling receptacle composedof an upper chamber 1 1 provided with a drain pipe l1', which isdesigned to hold the refrigerant, preferably ice, and a lower chamber 12designed for the accommodation of perishable erably restingon the bottomthereof is a coil inside walls with tin. This coil of pipe preferablyrests on end pieces 14 secured to the bottom of the chamber and whichare inclined transversely from one side to the other, so as to providefor a sufficient fall from the inlet of the coil to its outlet. 16 ofthe coil is in screw threaded engagement with an' inlet pipe 17 whichprojects through the front wall of the receptacle. The outer end of thisinlet pipe y17 projects upwardly and is provided on its outer end` withan annular flange 18, which is adapted to engage the inwardly couphng 20which is in screw threaded engagement with the receptacle holder 21,which in this instance is' shown as cone shaped so as to correspond withthe configuration of the open end of the liquid holdmg receptacle 22,which may be formed of any desired material. The inner face of thecone-shaped portion of the holder 21 is provided with a flexible pad 21to guard the lower end of the liquid receptacle against possible injury.

interposed between the outer end of inlet pipe 17 and the lower end ofthe receptacle holder is a rubber gasket 23 so .as to form a liquidtight joint. The neck 24 of the receptacle holder 21 passes through anaperture 25 in a bracket 26 which is rigidly secured to the outer faceof the cooling receptacle, a se't screw 27 preventing it from turning.The upper end of bracket 26 is provided with an a( justable slide arm 23which projects outwardly therefrom and is provided with a screw threadedaperture 29, through Which passes an adjusting screw 30, which has onits lower end a clamp 31 adaptedl to engage the up er end of the liquidholding receptacle, an to hold it firmly 1n place in the receptacleholder 21.

The liquid holding receptacle may be of any desired form, such as largedemijohns of water that are supplied to offices and families.

When it is desired to place the liquid holding rece tacle in itsoperative relation to the The inlet end turned flange 19 of a coolingyevice, the usual cork stopper is rst removed and a valve 32 is securedto the mouth of the receptacle. This valve consists preferably of-acylindrical elastic body 33 adapted to fit over the neck of thereceptacle, one of its ends being closed and provided with an outlet ort34. On the inner face of the closed en is a metallic plate 35 which isprovided with a similar port 36 which registers with port 34. Movablysecured to the outer face of valve 32 by means of a rivet 37 is ametallic plate 38 which is provided with a port 39 .similar in sha e tothe ports in the cylindricalelastic bo y of the valve and the metallicplate 35.

`tacle with the ports 3 4 and Metallic plate 38 is provided on itsperiphery with a pluralit of lugs 39 which are adapted to engage a puralityiof vertically disposedY grooves 40 on the,inner surface of theneck of the rece tacle holder 2T.

The out et end of the coil 13`is in screw threaded engagement with afaucet 41 which projects through the front of the coohng receptacle 10below the inlet to the pipe coil 13. This .faucet is provided with avalve stopper 42 which is adapted to engage a seat 43 near the inner endof the faucet and inside of the upper chamber 11, and is controlled byvalve stem 44 which is connected on its buterrend to the handle 45 bymeans of which thestopper is operated. The reason for pro,- viding thefaucet with a stopper near the inner endv is to insure the withdrawalfrom the faucet of liquid that has been cooled orv that is in closeproximity to the refrigerant.

If desired, the liquid holding receptacle could be permanently securedto the cooling device and to the coil, having an inlet in its top sothat liquid could be introduced to the receptacle as required.

The operation is as follows :#When it is desired to cool-the liquidcontained in a receptacle the stopper is first removed and the valve 32is secured to the mouth of the recep- 39 ,out of register, as shown inFigs. 4 and 5. The bracket 29 is then turned to one side and the liquidreceptacle is placed in the holder, the lugs 39 engaging the grooves inthe neck of the receptacle holder. The receptacle 22 is then turnedslightly so as to bring the ports 34, 36, and 39 into register with eachother, ythe liquid flowing through the coil 13 to the faucet 41, fromwhich it is drawn when desired.

It will be seen from the foregoing description that I have roduced aneconomical and an efficient coo ing device whereby large quantities ofliquid may be cooled as needed without encroaching upon any of the spaceof the cooling receptacle. l
